Is there air conditioning on a crewed yacht?

Yes — every cabin on a modern crewed yacht has air conditioning. Yachts over 45 feet built since 2005 ship standard with reverse-cycle AC in every guest cabin, plus the salon and galley. The AC runs on the yacht’s generator, which the crew typically cycles on overnight and during the hottest part of the afternoon. Some captains turn off AC at anchor in calm, breezy conditions and rely on hatches and overhead fans — quieter, lower fuel burn, and the cross-breeze on a Caribbean anchorage is usually plenty. Older monohulls and budget bareboats may lack AC in shared areas; the listing spec sheet calls out cabin-only vs. full-boat AC. Yacht spec sheets confirm the AC layout before booking.
